IMPROVEMENT IN BUTTON-HOLE CUTTERS.

Specification forming part of Letters Patent No. 128,902, dated July 9, 1872.

specification and represented in the accompanying drawing. Of such drawing- Figure 1 denotes a side elevation, and Fig. 2 alongitudinal section of the machine. Fig. 3 is a front-end view of its base-bar.

My invention consists in an improved construction or combination and arrangement of parts, as hereinafter described.

The said base-bar, shown at A, is a straight bar, provided at its front end with a recess, a, dovetailed in transverse section to receive a movable bed-piece, b, of any proper kind, such bed-piece being for supporting an article or garment while a button-hole may be in the act of being cut in it by the adjustable cutter B. This cutter can be reversed in the slot 01 of the arm E by removing and replacing the screw F, so that the eye-tube will either cut or not cut, as may be desired, forming a button-hole with or without an eye. The base-bar A is a straight bar, having an arched handle, (J, raised upon it, in manner as shown. It also has two curved standards, D D, raised upon it in advance of the handle, as shown, and parallel to each otherf A slotted arm, E, arranged between and pivoted to the standards in advance of the handle, as shown at 0, supports in a slot, 01, the adjustable cutter B, which is pressupward the cutter-arm, which is actuated in the opposite direction by a cammed or bent lever, H, pivoted to the standard, as shown at g, there being a stop-pin, h, going through the standards to estop the upward movement of the lever. Furthermore, in the base-bar, and arranged as shown, is an adjust able gauge, I, provided with a long slot, 6, in its shank. The said gauge is held to one of the standards by a clamp-screw, k, which goes through the slot t and screws into the standard. The larger arm of the lever extends backdirectly over the arched handle, in order that a person, when his third and fourth fingers are extended through the arched handle, may, with his thumb or the palm of his hand, actuate the lever so as to cause the cutter to be moved down toward the bed. The adjustable gauge is to support the edge of a garment or article, next to which a button-hole is to be made, and is to regulate-the distance of the cut from such edge.

I make no claim to a cutter, as described, made adjustable, as explained, with respect to a bed, the bed and cutter being applied to separate levers, curved and connected like the blades and handles of scissors.

What I claim is- The improved machine, as composed of the base-barA, the arched handle 0, the two standards D D, the slotted cutter-arm E, the adjustable and reversible cutter B, the elevating spring G,the cammed lever H, and the adjustable edge-gauge I, arranged and combined in manner and to operate substantially as described.
